WebKw relates the concentrations of hydronium and hydroxide. When trying to convert from one concentration to another, like when using the happy fun wheel, Kw can be very useful. Rather than going around the entire wheel and doing excessive conversions, Kw can get you from the concentration of hydronium to hydroxide (and vise versa) in one calculation.
